ET sat down with creator Marlene King at the ATX Television Festival in Austin, Texas to get the inside scoop on absolutely everything 'PLL' fans need to know before tuning into 'Pretty Little Liars: The Perfectionists'.

ET caught up with the actress at Freeform's Upfront presentation in New York, where she also promised there is still hope for 'Emison.' 'Pretty Little Liars: The Perfectionists' comes to Freeform in 2019.
